JAMES PRCE. AND. WILLIAM Gr. WINTER,- OF HOLLAND, MICHIGAN.

FUMIGATOR.

Specification of Letters Patent.

Patented Dec. 23, 1913.

To all/whom may concern Be it known that we, JAMES PRICE and WILLIAM G.WINTER, citizens of the United States of America, residing at Holland,in the county of Ottawa and State of Michigan, have invented certain newand useful Improvements in Fumigators; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

Our invention relates to improvements in f'umigators, and moreparticularly to that class of fumigators wherein heat is applied toevaporate the germicide, and its object is to provide a container fortransporting both the germicide and the fuel by which it is evaporated,and to adapt the container to be converted into a burner and evaporatingpan for use in evaporating the germicide; and to provide a devicecombining these features which may be cheaply and easily constructed,which shall be simple and effective in operation, which may be readilyand safely used by the novice, and furthermore, to provide such devicewith various other new and useful features as hereinafter more fullydescribed and particularly pointed out in the claim.

It has been found that there is general demand for a simple, Safe andeffective fumigator which is inexpensive and adapted to be put intoeffective use by an inexperienced person, and which will perform itsfunction without entailing the danger of accidental coniagrations,explosions, etc.

Our invention supplies all of these various requirements, and comprisesa cup-like germicide receptacle to contain the germicide which ispreferably of a semi-solid nature, and which is adapted to be evaporatedby applying heat thereto. This germicide receptacle also serves as anevaporating pan when the fumigator is in operation. A fuel receptacle isalso provided which is of a shallow cup-like form and contains the fuelvwhich is preferably paraiin or like inlam mable substance having a wickembedded therein. This fuel receptacle is adapted to be inverted and litover the germicide receptacle to form a closure for the same duringtransportation of the device. In operating this device as a fumigatorthe fuel receptacle is placed beneath the germicide container, the saidcontainer being supported by a drum which surrounds its lower portionand extends downward therefrom and is adapted to receive the fuelreceptacle at its lower end. The drum serves as a body for the burnerandis provided with a multiplicity of perfo-rations to admit air to theburning fuel, and also act as a fire stop, preventing the llame fromescaping outside of the perforated drum and igniting the gases whicharise from the germieide.

The device is provided with various other novel features of constructionand arrangement as will more fully appear by reference to theaccompanying drawings; in which,

Figure 1 is a side elevation of a device embodying our inventionassembled for transportation; Fig. 2 is a sectional elevation of thesame Fig. 3 is a side elevation of the device ready for operation; and,Fig. 4 is a sectional elevation of the same.

Like numbers refer to like parts in all of the figures.

l representsy the cylindrical cup-shaped germicide container which ispartially filled with the germicide 2, which in the form shown, has beenpoured into the retainer in a molten state, and in its cooled andsuliiciently solid state is now retained in position at the bottom ofthe container by means of an inwardly extending annular bead 3. The fuelreceptacle 4 is also of cylindrical cup-like form, being shallower thanthe germicide container, and prefer-ably its inner curved surfaceextends in radial direction as shown in order to retain in position thefuel 5 which has been poured in molten condition into the receptacle.The wick 6, which is preferably conical in shape, having its apexpointed upward, is embedded in and held by the fuel, having been placedin the receptacle 4 while the fuel is still in a molten state. The fuelreceptacle near its mouth is of less diameter than the germicldecontainer near its mouth, and is adapted, when inverted, to betelescopically held within the said germicide container, and in thisposition it serves as a closure for the germclde container for thepurpose of transportation.

The lower end of the germicide container is adapted to be telescopicallyheld by a cylindrical supporting drum 7 whose lower end is adapted totelescopically hold the portion of the fuel receptacle near its mouth,when the same is used as a burner, and to be supported thereby, theupper edge of this drum engaging the outwardly7 extending annular bead Sof the gerlnicide container. When the fuel rece )taele is in such)osition in the lower end o this drum the rum serves as a body of theburner, and is provided with a multiplicity of erforations, as shown, toadmit air to the urning fuel and also to act as u fire stop, preventingthe flame from escaping outside of the perforated drum. When in thisoperative position the fuel receptacle rests upon a number of raisedportions 9 which extend from the bottom thereof and space it away fromthe surface upon which it rests so that air may circulate under thebottom to prevent. over-heating.

The user receives this fumigator as it has been assembled fortransportation, as shown in Figs. 1 and 2, the fuel receptacle, beinginverted and fitted into the upper end of the germieide container, andthe drum telescoping the lower end of the said container. To put thedevice into operation it is necessary only to remove the fuel receptacleand place it right side up, light the a x of the wick, and then (it thelower end o the drum over the upper end of the fuel receptacle,whereupon the fuel will burn and evaporate the germicide within thecontainer. The perfor-ations in the drum admit enough air to the flameto produce a proper combustion and at the same time the drum confinesthe flame within it, preventin the accidental igniting of the gases whicrise from the evaporating germicide und thus eliminating the danger ofconfiagrations and explosions. The relative pro ortions of fuel andgermicide should be suc that there will be only sufficient fuel toevaporate all of the germicide within the container.

It will be seen that this invention affords a simple, safe and effectivedevice for accomplishing the desired result, and the device may becheaply made and put on the market at a low price. It is also verycompact for shipping purposes, storage, etc.

Not confining ourselves to the exact construction herein shown ordescribed, what we claim is:

A fumigator, comprising a cup like germicide container partially filledwith a semi-Solid germi'cide, an extension on the inner surface of thegermicide container to retain the germicide, a cup like fuel containerhaving a circumferential enlargement to retain a semi-solid fuelsubstance and a wick embedded in the fuel, a drum adapted to receive thegermicide container at one end and the fuel container at the other endand forming therebetween a combustion chamber. the wall of said drumbeing perforated throughout to admit air for combustion, but theperforations being fine enough to form an effective fire stop, externalcircumferential shoulders on both of said containers to engage therespective ends of said drum, the fuel receptacle being adapted to titinto the mouth of the germicide container when packed for shipment, andfor operative position to be removed therefrom and inserted into the endof the drum opposite the germicide container.

In testimony whereof we affix our signatures in presencel of twowitnesses.
